Stone can degrade as well. Basalt can absorb CO2 [1], marble is vulnerable to acids [2], and generally acid rain is a huge problem for historic buildings [3], as is bird poop [4].

Probably the only material impervious to damage is diamonds.

Diamonds burn, and have the same problem as precious metals: getting stolen and repurposed.

And obviously you’d pick your stone based it’s characteristics and the environment, you wouldn’t record your message to the next generation on pumice.
